(Description of security code in FIG. 5)
As shown in FIG. 5, the security code includes a security code on the main side and a security code on the sub side.

As shown in FIG. 5A, the main-side security code is stored in a plurality of main-side tables, for example, three types of main-side table 1, main-side table 2, and main-side table 3, respectively.
In addition, the kind of main side table is not limited to three types, What is necessary is just two or more types, and two types or four types or more may be sufficient.

In each main side table, a main side security code is stored for each main side code number.
For example, as shown in FIG. 5A, the main side code number “0” of the main side table 1 includes “9012” and “1” which are security codes composed of four decimal digits. “5264”, “2478”, “5326”, “5326”, “4356”, “4356”, “5265”, “4265”, respectively. Yes.

In addition, although the 4-digit number of the decimal number was illustrated as a security code, it is not limited to this.
The three types of main table 1, main table 2, and main table 3 are stored in the main table storage unit 361 shown in FIG.
The main side code number starts from “0” and is finite, for example, set to “3,000”.

As the main code number. Although “0” to “3,000” are exemplified, the present invention is not limited to this.
As shown in FIG. 5 (b), the sub-side security code is configured in the same manner as the main-side security code shown in FIG. 5 (a), and has the same number of sub-side tables as the main-side table, for example, three types. Are stored in the sub-side table 1, the sub-side table 2, and the sub-side table 3, respectively.

The sub-side table 1, the sub-side table 2, and the sub-side table 3 are stored in the sub-side table storage unit 441 shown in FIG.
(Security management method)
Next, a security management method by the slot machine 10 having the above-described configuration will be described.

  First, when the power of the slot machine 10 is turned on, the table lottery means 362 of the main control means 300 in FIG. 1 stores three types of main side tables (see FIG. 5A) stored in the main side table storage means 361. One type of main side table is selected by lottery. It is assumed that, for example, “main table 2” in FIG. 5A is selected from the three types of main table 1, main table 2, and main table 3.

1 transmits a table number corresponding to one type of “main table 2” selected by the table lottery means 362, for example, the number “2”, to the sub-control means 400.
When the sub-control unit 400 in FIG. 1 receives the number “2”, which is the table number transmitted from the data transmission unit 370 via the data reception unit 410, stores the table number in the table number storage unit 442.

On the other hand, when the start switch 70 shown in FIGS. 1 and 4 is operated after inserting medals, rotation of the three reels 31 to 33 starts.
At this time, the lottery is executed by the game result lottery means 310 of the main control means 300 of FIG.
For example, assume that a small role is won by lottery.
As a result, game information including a command and data corresponding to winning of the small role is transmitted to the sub-control unit 400 via the data transmission unit 370 of FIG.

When the game information such as a command is transmitted, the main-side code number calculating unit 364 in FIG. 2 divides the game time measured by the main-side game time measuring unit 363 by a predetermined update interval (for example, “1.49 ms”). The main code number is calculated.
Since the power is turned on, the game time is “0 ms”.
Therefore, when the game time is divided by “0 ms” by the update interval “1.49 ms”), the main code number becomes “0”.

The main-side security code reading means 365 in FIG. 2 collates with one type of main-side table selected by the table lottery means 362, here “main-side table 2” in FIG. The main security code corresponding to a certain number “0” is read.
As shown in FIG. 5A, the main-side security code corresponding to the main-side code number “0” in the “main-side table 2” is “4425”.

The main-side security code reading unit 365 in FIG. 2 transmits the read main-side security code to the sub-control unit 400 via the data transmission unit 370.
The command and the main security code are included in the game information as a set and are transmitted to the sub-control unit 400 at the same time.
When the sub-control unit 400 receives the game information, the sub-side code number calculation unit 444 in FIG. 3 displays the game time measured by the sub-side game time measurement unit 443 by the main-side code number calculation unit 364. The sub-code number is calculated by dividing by the same update interval (for example, “1.49 ms”) as the update interval.

Since the power is turned on, the game time is “0 ms”.
Therefore, when the game time is divided by “0 ms” by the update interval “1.49 ms”), the main code number becomes “0”.
The sub-side security code reading unit 445 in FIG. 3 collates with one type of sub-side table corresponding to the table number stored in the table number storage unit 442, here “sub-side table 2” in FIG. 5B. The sub security code corresponding to the sub code number “0” is read.

As shown in FIG. 5B, the sub-side security code corresponding to the sub-side code number “0” in the “sub-side table 2” is “4425”.
The security code comparison means 446 in FIG. 3 includes the main side security code transmitted by the main side security code reading means 365 in FIG. 2, here “4425”, and the sub side security code read by the sub side security code reading means 445. Here, “4425” is compared.

As a result of the comparison, the main security code “4425” and the sub security code “4425” match, so the command included in the game information is valid.
The image control means 420 and the sound effect generation means 430 in FIG. 1 display an image corresponding to the command or the like transmitted from the main control means 300 and display the corresponding sound effect on the image display device 40. Output from 100,101.
(Error notification)
On the other hand, the main-side security code transmitted from the main control means 300 in FIG. 1 is “0”, which is the main-side code number of “main-side table 1”, regardless of the first game after the power is turned on. It is assumed that the main-side security code corresponding to the number is “9012” as shown in FIG.

As described above, when the power is turned on, the table number transmitted from the main control unit 300 in FIG. 1 is “2”, and the “2” is stored in the table number storage unit 442 in FIG.
When the sub-side security code reading means 445 of FIG. 3 collates with the “sub-side table 2” of FIG. 5B and reads the sub-side security code corresponding to the sub-side code number “0”, “ 4425 ".

The security code comparison unit 446 in FIG. 3 compares “9012”, which is the main-side security code, with “4425”, which is the sub-side security code.
As a result of the comparison, since the main security code “9012” and the sub security code “4425” are different, it is determined that the command included in the game information is invalid.

The error notification means 447 in FIG. 3 notifies an error to the outside. For example, a warning sound is generated from the speakers 100 and 101 of FIGS. 1 and 4, a warning image is displayed on the image display device 40, or a so-called hall computer is notified although not shown.
Further, the game is stopped by the game stop means 448 of the error notification means 447 of FIG. For example, the insertion of medals from the medal insertion slot 50 in FIG. 4 is disabled, all inserted medals are returned, or the operation of the start switch 70 is disabled.
(Game time measurement)
In the second and subsequent games after the power is turned on, the game time is measured by the main game time measuring means 363 in FIG.

2 measures the time from the operation of the start switch 70 to the next operation of the start switch 70 as one game time.
The game time measured by the main game time measuring means 363 is assumed to be “3,700 ms”, for example.
If the game time “3,700 ms” is divided by the update interval “1.49 ms” by the main side code number calculation means 364 in FIG. 2, the main side code number becomes “2,483”.

When the main side code number calculated by the main side code number calculating means 364 exceeds the maximum number of “3,000” which is the maximum value of the main side code number, it is counted again from the “0” number. , Loop and use.
The sub-side game time measuring means 443 in FIG. 3 also measures under the same continuation condition as the main-side game time measuring means 363 in FIG.

According to the present embodiment, a security code is used for communication between the main and the sub, and both security codes are updated on the time axis, so that it is simpler than the case where the data encryption method is adopted. Therefore, it is possible to provide a security system suitable for slot machines.
